Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X175-75STC
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X175-75STC is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 175mm stroke, G1/2 air ports and adjustable end cushioning. Its no-tie-rod, hard-anodized profile barrel is more compact than an ISO 15552 cylinder of the same bore — a space-saver on tight machines.

About the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X175-75STC
The hard-anodized aluminum barrel keeps the build shorter and more compact than a same-bore ISO 15552 unit.
The external stop screw provides a 75 mm on-site extend-shortening window, letting you dial in the usable stroke anywhere from 100 to 175 mm without swapping the cylinder. Air connects via a G1/2 port, and the -S suffix means a built-in piston magnet is present for side-groove CMSE/DMSE sensors. Remember that the adjustable stop sets the end position but does not lock the load; you need an external rod lock or pilot-operated check valve to hold a vertical load securely against air loss.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3525 N | 3525 N |
| 0.7 MPa | 4935 N | 4935 N |
| Max (@1.0 MPa) | 719 kgf | |
JSIJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative).

Where the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X175-75STC Is Used
Press Fit Tuning
Dial in the exact 100 to 175 mm extend position for seating bearings without machining custom spacers or changing the entire actuator.
Variable Transfer Stops
Adjust the extend stop on-site to accommodate different package sizes on a single line, using the TC mount to pivot smoothly.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X175-75STC the Right Cylinder?
When sizing this 100 mm bore, stepping down to an 80 mm cylinder drops the 0.5 MPa push force to 2513 N, while moving up to a 125 mm bore jumps it to 6136 N. The 75 mm adjustable window is ideal for sharing a single spare across multiple stroke variants or fine-tuning the extend end position on-site. The TC trunnion mount supplied gives you a pivoting centerline axis. Because this SKU includes the -S magnet, you can fit CMSE or DMSE reed and electronic switches directly into the barrel grooves. For any stroke length at or above 300 mm, always guide the load externally to prevent side-load damage to the rod and front cover.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Set cushions to minimum, then release gradually.
- check Use correct mounting accessory (LB/FA/FB/CA/CB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X175-75STC FAQ
At 0.5 MPa this 100 mm bore cylinder pushes with 3927 N and pulls with 3574 N. At 0.7 MPa the push is 5497 N and the pull is 5003 N. The theoretical maximum force is 801 kgf at 1.0 MPa. The air port size is G1/2.
The nominal 175 mm stroke is the maximum extend length. An external adjuster screw lets you shorten the extend stroke on-site by up to 75 mm, giving a usable extend range of 100 to 175 mm. The retract end remains fixed. This mechanism only sets the end position and does not lock the load.
